SPECIFICATION forming part of Letters Patent NO."78 1,50-I, dated January 31, 1905.

Application filed Au ust 11,1904. Serial No. 220,353.

To all whom it may concern:

had to the accompanying drawings, and to let, ters of reference marked thereon, which form a part of this specificationl Figure 1 is a perspective view of the invention applied to a surface-lock. .Fig. 2 is a sectional view on line 2 2 of Fig. 1. Fig. 3 is a View of the invention applied to a rnortiselock. Fig.4 is a sectional view on line 4: i

of Fig. 3. Fig. 5 is a perspective view of the invention, the plates closed and the abutmentbolt in position. Fig. 6 is aperspective view of the abutment-bolt. Fig. 7 is a viewshowing the'plates opened apart.

The object of this invention is to provide a portable safety door-securer for the use of travelers and others needing such a device; and it consists in the novel construction and combinations of parts, as hereinafter set forth.-

In the accompanying drawings, illustrating the invention, the letter a designates an oblong rectangular plate which is hinged by one end to a plate 6, which is of similar form. These plates are adapted to fold together flatwise, as shown. The inner plate a is provided near its free end with a transverse slot 0, and it has also a longitudinal slotv (Z extending from the transverse slot 0 to the hinge portion. On each side of the longitudinal slot (Z is made an aperture 6, usually of square form,

these apertures being about three-quarters of e an inch from the transverse slot. In the lon gitudinal slot is provided a slide-piecef, which is about one-half inch in length and is designed gether.

5 a tongue in plateb and bending it at rightangles to the plate, as indicated. The lug should be at least a quarter of an inch in depth, so as to project beyond plate a when the plates are closed. The edge of the lug is usually made acute. The plate 7) is also provided with lateral apertures it h, similar to the lateral apertures e c of plate a and in like position, so that when the plates are closed together the aperture it of plate Z) will register with the aperture 6 of plate (0.

Connected by a chain to the outer end of the device is the abutment-bolt m, which is ofblock form and is provided with bolt-lugs p 0,

adapted to engage the locking-apertures of plate 6 or those of plate a and plate 6 when these plates are closed together. The abutment-bolt 11?. has one of its faces flush with the edges of thebolt-lugs, while its opposite face is offset because of the shouldered projection q. The abutment-bolt is so made in order that by its reversal the securer may be ,adjusted in accordance with the requirements. A pivoted spring-keeper s is provided in connection with the securer to aid in holding the abutment-bolt in place.

In using this securer on a common door having an outside lock and-bolt-hasp the hingeplates are brought together and the slide-piece f ismoved along its slo'tway to the lug .is anchored Within the hasp prevents the door from being opened. In the case of a mortiselock the plates are closed together and the slide moved away from the lug g to the hinge end of its slot. The lug g is then placed in the latch-mortise in the door-casing and the door shut. .Then the abutment-bolt is engaged with the bolt-apertures of the plates, as in the the latch-mortise by the lug g the engagement of the abutment or block portion of the bolt with the door-face holds the door secure. the doorfits against the jamb in a close man- IOO ner. the plates a and b may be opened apart and plate 6 used between the edge of the door and the casing, plate a being moved to one side. The offset side of the abutment-block is turned toward the door if the distance between the face of the door and wall of the mortise is comparatively small.

Having described the invention, What I claim, and desire to secure by Letters Patent,

1. A portable door-lock, having in combination, a longitudinally-slotted plate having an anchor-lug and lateral bolt-apertures, a reversible abutment-bolt having lugs to engage said apertures. a slide-piece in the slot of the plate, aconneeting-chain, and a spring-keeper for said bolt, substantially as specified.

2. A portable door-lock, having in combination, a main plate having an anchor-lug and lateral bolt-apertures, an inner plate hinged thereto having an adjustable sliding piece, and lateral bolt-apertu res adapted to register with those of the main plate, an abutment-bolt adapted to engage the bolt-apertures of said plates, and a chain connecting said abutmentbolt, and the lock-plates, substantially as specified.

In testimony whereof I afiix my signature in presence of.tWo Witnesses.

WARD P. DOBSON.
